<LI> ... altering the density of the patterns using the method <A href="../ref/PlotBand.html#_PLOTBAND_SETDENSITY">
 PlotBand::SetDensity()</A> The density is specified as an integer in
 range 1 to 100 where a higher number means a higher density (smaller
 distance between the lines). For example setting the density of the 3D
 plane above to 60 gives the result<DIV class="example">
